TECHNICAL FIELD

This invention relates to a hair brush for use in a hairdressing store, a beauty shop, or at home, and more particularly, to a hair brush which is able to easily and freely create a hair style by arranging frictional brush pins to a brush portion of the hair brush so that the hair is easily entangled around the brush portion.

BACKGROUND OF THE INVENTION

Conventionally, as a means for forming a curl of the hair based on an effect of heat, there is a hair iron brush which twists hair around the iron part provided with a heating element. This hair iron brush has a hair pressing part (clip) which holds the hair in combination with a brush portion. The hair is held between this clip and the brush portion thereby forming a desired shape of the hair (hair styling), such as a curl, a straight, etc.

Patent documents 1 and 2 disclose such a conventional technology of the hair iron brush provided with such a clip.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention

In the conventional technology disclosed by the patent documents 1 and 2, since the hair pressing part (clip) is provided, when the hair is rolled by clipping the tip of the hair between the hair pressing part and the brush portion, it becomes impossible to open and close the hair pressing part because of the hair rolled around the hair pressing part, thus, arises a problem in that it is difficult to remove the hair brush from the hair.

In order to remove the hair iron brush from the hair, after rolling the hair from the hair tip, it must rewind the hair to the hair tip. However, in this rewinding process, the hair is likely pulled, thus, there is also a problem that the hair curl or hair shape is broken or lost by the remaining heat from the hair iron brush.

Since the hair pressing part is used to clip the hair, when a middle portion of the hair is clipped, shorter hair is also clipped together, it becomes difficult to roll the hair since the shorter hair hinders the rolling movements of the hair brush, which makes it impossible of hair styling. It is also impossible to carry out a particular styling in which the hair brush rolls the hair from the root of the hair toward the tip of the hair.

It is therefore an object of the present invention to provide a hair brush which is easy to tangle with hair by arranging frictional brush pins on a brush portion of the hair brush.

It is a further object of the present invention to provide a hair brush which enables various hair styling with ease and free.

It is a further object of the present invention to provide a hair brush which includes a multi-element mineral powdery material or a far-infrared radiation powder material to achieve effective hair care and scalp care in addition to the hair styling.

DESCRIPTIONS OF THE PREFERRED EMBODIMENTS Embodiment 1

As shown in FIGS. 1 to 4, the hair brush according to the first embodiment of the present invention comprises a main body of a straight structure having a grip portion 1 at the base portion and a brush portion 2 at the front portion, and can be folded at the center portion of the main body through a bending portion 3.

The grip portion 1 has a substantially cylindrical shape for gripping. A power cord 4 is connected to the base end of the grip portion 1, a power switch 5 is provided at the front center of the main body, and a folding switch 6 is provided at the center on the back side of the main body.

The brush portion 2 is disposed on an extended line of the grip portion, and brush pins are erected radially on the outer periphery of the fixed cylindrical seat.

A heating element is housed inside the fixed cylindrical seat, and receives electric power from a power cord 4 connected to the grip portion 1 to generate heat.

The brush pins provided upright on the brush portion 2 are composed of frictional brush pins 7 having friction property with respect to the hair and slippery brush pins 8 having slippery property with respect to the hair.

The frictional brush pins 7 are slightly thicker than the slippery brush pins 8.

The frictional brush pins 7 and the slippery brush pins are erected so as to form each brush pin row in the longitudinal direction of the main body. Each brush pin row is arranged with a predetermined angle (30 degrees in this embodiment) with one another, and the brush pins are arranged in a manner of circling around the fixed cylindrical seat.

That is, in the present embodiment, one to fifteen pins in line of the frictional brush pins 7 or the slippery brush pins 8 constitute one brush pin row, and the brush pin row has an angle of 30 degrees with respect to the other brush pin row in the circumferential direction of the fixed cylindrical seat.

In the present embodiment, for example, the total of twelve brush pin rows are arranged on the brush section 2, in which three rows of the frictional brush pins are arranged at an interval of 120 degrees, while nine rows of slippery brush pins are spaced apart as shown in FIG. 4.

Each of the frictional brush pins 7 is made of a flexible material such as fluoro rubber, and a surface thereof is roughened by numerous irregularities. The frictional property created by such a rough surface treatment functions for adhering the hair at the time of hair styling.

It should be noted that each of the frictional brush pins 7 can be formed of other materials such as synthetic resin, silicon, or the like, and its surface can be smoothly formed without forming irregularities.

On the other hand, each of the slippery brush pins 8 is subjected to a surface smoothing process to achieve a low frictional resistance similar to that of a normal comb.

As shown in FIG. 3, the shape of the frictional brush pin 7 is such that the base portion is short and rises linearly, the short side rising portion gradually widens and the central portion thereof is the widest. Then, from the widest central portion to the tip end, the width gradually decreases. Therefore, when viewing the frictional brush pin 7 from the side, it has a diamond shape.

The distance between the adjacent frictional brush pins is such that the tip part is opened toward the front (radial direction), gradually narrowed towards the center, and the base part is further widened, so that at the time of brushing, the hair is easy to fit from the widely opened tip portion, and the hair once fitted to the base portion of the frictional brush pins 7 is prevented from coming off due to the narrowed portion at the center and is hard to come off from the brush pins.

In this embodiment, the interval between the narrowed portions is 0.5 mm.

The interval of the narrowed portion is preferably in the range of 0.5 to 1 mm, and further, it can be implemented within the range of about 0 to 2 mm.

Accordingly, the frictional brush pins 7 grip the hair by the frictional property at the time of hair styling. However, when the angle or strength of the main body is adjusted by operating the grip portion, the hair fitted to the base portion can pass through the base portion and can be released from the hair brush.

A heat plate is arranged on the fixed cylindrical seat on which the brush pins are erected. This heat plate receives heat from the heating element in the main body and provides an ironing effect to the hair. Thus, the hair contacting the heat plate is styled by the ironing effect.

Since the rising surface of the frictional brush pins 7 is connected in a state in which rubber is exposed in the row direction, this portion is formed slightly lower than the adjacent heat plate. That is, the heat plate is positioned on the front (outer) side of the rubber so as to be slightly protruded, thereby making it easy for the hair to come into contact with the heat plate.

Next, a method of using the hair brush of this embodiment will be described.

First, turn on the power switch 5 to energize the heating element so as to heat the rising surface of the base portion of the brush portion 2.

When the temperature reached an appropriate temperature, the hair is rolled up with the brush portion 2, or the hair is drawn by the brush part 2, and thus, the hair is shaped into a curl, a wave, or a straight.

Since the frictional brush pins 7 are provided, at the time of brushing, the hair is easy to fit from the open tip portion, and the hair once fitted to the base portion of the frictional brush pins 7 is prevented from coming off by the narrowed portion at the center of the frictional brush pins 7 and thus is difficult to be released.

Since the hair brush of this embodiment will not clip the hair but entangle the hair with the frictional brush pins 7, even if it is at the tip of the hair or the middle part thereof, the frictional brush pins can easily entangle the hair and a user can easily form curls and waves on the hair, or the user can stretch the hair straight.

That is, while rolling the hair from the tip of the hair, the user can also roll the hair through the root or middle part of the hair, or the user can simply straighten the hair.

When the grip portion is rotated or tilted in a direction to loosen the entanglement at the time when curl, wave, or straight shaping is sufficiently performed, the tangling of the hair with the frictional brush pins 7 is released, and accordingly, the brush portion 2 is separated from the hair.

As has been described above, in the present embodiment, the frictional brush pins 7 of flexible material are provided, and since a narrowed portion where the hair hardly drops is formed on the flexible frictional brush pins 7, and the gap between the frictional brush pins 7 is brought close to each other, it is easy to grab the hair, while it is hard for the hair to escape.

In addition, since the frictional brush pins 7 are formed of the flexible material, a good resistance force is applied to the hair, which appropriately aligns the hair skin (cuticle) thereby enabling to shine the hair.

When carrying around the hair brush of the present invention, it is able to easily make it small (into half) by folding the hair brush at the bending portion.

Embodiment 2

Next, a hair brush according to the second embodiment will be described.

In the hair brush of the second embodiment, it is characterized in that either the frictional brush pins 7 or the slippery brush pins 8 in the first embodiment or both the frictional brush pins 7 and the slippery brush pins 8 and the surface of the heat plate in the first embodiment contain a multi-element mineral powdery material or a far-infrared radiation powder material.

In the hair brush of this embodiment, an ironing effect can be effectively obtained by far infrared rays radiated from the far-infrared radiation powdery material.

Because of the multi-element mineral powdery material, it is possible to conduct hair styling while caring for the hair with weak energy emitted from the powdery material and to promote hair growth and effective scalp care by improving the blood circulation of the scalp.

Further, even when brushing the hair, because of the action of the multi-element mineral powdery material, static electricity is not generated, thus, curling of the hair and the like by brushing and the heating plate can be performed smoothly, and as a result, hair styling can be easily achieved.

Moreover, by brushing with minus ions generated from the multi-element mineral powdery material, it is possible to improve the blood circulation of the hair and scalp. Further, the cluster phenomenon (the ability to reduce the molecular group of water) in the moisture of the hair is caused by the minus ions, it is possible to improve the hair gloss feeling and moisturizing feeling, thereby enabling to finish the hair with a smooth and sleek design.

In addition, the minus ions act on cuticles (fibers in glassy state) of the hair, so that they can always be kept in good condition, and in particular, it is effective for damaged hair as well as thin and uncontrollable hair.

The multi-element mineral used in the present invention refers to a mineral whose main component is silicon, such as perlite, pine rock and tourmaline (electric stone), and contains many elements in a well-balanced manner. It is known that the multi-element mineral emits minus ions.

The multi-element mineral powdery material is formed by pulverizing the multi-element mineral with a ball mill or the like. The pulverization value in this case is preferably 1 to 3 microns, although this numerical value may be changed.

The multi-element mineral powdery material can be used singly or in combination, although it is preferable to use the combination of two or more kinds as appropriate.

This multi-element mineral powdery material may be used as is or after it is mixed with water and heated or pressurized, and then, the supernatant liquid is made into a powdery form via a vacuum freeze drying process or a spray drying process.

The term “contain” (see paragraph [0028]) as used in the present invention includes not only those formed into a predetermined shape by kneading a multi-element mineral powder or far-infrared radiation powder in the frictional brush pins and the slippery brush pins itself, as well as a coating layer (for example, a ceramic coating layer, a plating layer, a fluorine coating layer, a nylon layer, a synthetic resin layer, a silicone rubber layer, a fluorine rubber layer, etc.) created by coating the multi-element mineral powdery material or the far-infrared radiation powdery material after mixing with a coating agent and applying the mixture on the brush pins and/or the heating plate.

Regarding the method of forming the ceramic coating layer, for example, a method in which the multi-element mineral powdery material or the far-infrared radiation powdery material is added to a heat-resistant formica as a coating agent to make the mixture into a paint form which is applied to the brush pins, and then the brush pins are passed through a heating furnace for blowing (baking) the coating agent.

The mixing ratio of the multi-element mineral powdery material or the far-infrared radiation powdery material to the heat-resistant formica is preferably 3 to 15% by volume, although the mixing ratio is not limited to this value.

Then, in order to mix the multi-element mineral powdery material in the frictional brush pins or the slippery brush pins, for example, the multi-element mineral is pulverized to about 1 to 3 microns by a ball mill, a jet mill or the like to form a powdery body, and this powdery body is mixed with raw materials of the multi-element mineral (for example, molten metal, molten resin) at a ratio of 5 to 10%.

In this case, it is preferable that two or more kinds of multi-element mineral powdery materials are suitably blended and used, although one type thereof may also be used.

Alternatively, the multi-element mineral powdery material may be mixed with water, heated or pressurized, and the resultant supernatant may be mixed, or powders prepared through a vacuum freeze-drying process or a spray drying process may be mixed.

The components of perlite, an example of multi-element minerals, are shown in the list below.

cilicic oxide (SiO₂) 71.94% aluminum oxide (Al₂O₃) 14.94% ferric oxide (Fc₂O₃) 2.54% magnesia oxide (MgO) 0.44% calcium oxide (CaO) 2.47% alkaline oxide (K₂O + Na₂O) 6.87% manganese oxide (MnO) 0.03% phosphoric oxide (P₂O₃) 0.14% ignition loss 3.43% drying loss (at 110° C.) 0.07% other titanium trace

In the above list, ignition loss conforms to that of cosmetic standard of kaolin (500° C., constant temperature).

Examples of the far-infrared radiation powdery material includes alumina (Al₂O₃), titania (TiO₂), ferrite (Fe₂O₃), chromium oxide (Cr₂O₃), silica (SiO₂), yttria (Y₂O₃), magnesia (MgO), etc., can be used singly or in combination.

Although the embodiments of the present invention have been described above, specific configurations of the present invention are not limited to that described with respect to the first and second embodiments, and even if there is a change in settings or the like not deviating from the gist of the invention, such modifications are within the scope of the present invention.

For example, as for the shape of the frictional brush pins 7 described in the first embodiment, in addition to the diamond shape, other shapes can be adopted as long as it has a configuration for creating a narrowed portion with the adjacent brush pins.

Further, in the first embodiment described above, although the frictional brush pins 7 are arranged in three rows at the interval of 120 degrees, it is also possible to arrange them in four rows at intervals of 90 degrees. That is, the number of rows to be arranged is arbitrary, and even in the case where fewer or more frictional brush pins are arranged than that of the present embodiment, such modifications are within the scope of the present invention.
